Development and dosimetric evaluation of a freely deformable ⁶Li-based neutron shield for boron neutron capture therapy. [PDF]

Med Phys
Abstract Background Boron neutron capture therapy (BNCT) enables selective tumor irradiation by exploiting the high‐linear energy transfer particles generated from neutron interactions with 10B atoms. BNCT has been approved as an insurance‐covered medical treatment for recurrent head and neck cancer in Japan.

Investigation on the efficacy of a tissue equivalent material bolus for BNCT. [PDF]

J Appl Clin Med Phys
Abstract Background In radiation therapy, the use of bolus is an effective technique for improving the surface dose. This irradiation technique is also used in BNCT. However, since BNCT uses neutron irradiation, it is important to evaluate both the neutron moderation characteristic and the radioactivation of the bolus.

Epithermal neutron instrumentation at ISIS [PDF]

Journal of Physics: Conference Series, 2014
The advent of pulsed neutron sources makes available high epithermal neutron fluxes (in the energy range between 500 meV and 100 eV). New dedicated instrumentation, such as Resonance Detectors, was developed at ISIS spallation neutron source in the last years to apply the specific properties of this kind of neutron beam to the study of condensed matter.
